equipment in space. Duct cross-sectional area shall be same as opening free area.

3.Horizontal ducts. Minimum free area of 1 square inch per 2,000 Btu per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area.

Alternate method for boiler located within confined space. Use indoor air if two permanent openings communicate directly with additional space(s) of sufficient volume such that combined volume of all spaces meet criteria for unconfined space. Size each opening for minimum free area of 1 square inch per 1,000 Btu per hour input of all equipment in spaces, but not less than 100 square inches.

4.Louvers and Grilles of Ventilation Ducts

All outside openings should be screened and louvered. Screens used should not be smaller than ¼ inch mesh. Louvers will prevent the entrance of rain and snow.

a.Free area requirements need to consider the blocking effect of louvers, grilles, or screens protecting the openings. If the free area of the louver or grille

is not known, assume wood louvers have 20-25 percent free area and metal louvers and grilles have

60-75 percent free area.

b.Louvers and grilles must be fixed in the open position or interlocked with the equipment to open automatically during equipment operation.

SINGLE MANIFOLD BASE 5006B

THRU 5014B SECTION BOILERS

1.BASE-BURNER-MANIFOLD ASSEMBLY(S).

a.6 section thru 14 section boilers require single base assembly, see Fig. 2.

b.15 section thru 26 section boilers require a left and a right base subassembly, see Fig. 3.

Remove Base Assembly(s) From Skid(s)

c.Remove bolts securing Base Assembly(s) to shipping skid(s) and place Base(s) in location where Boiler is to be installed.

d.Join Base Sub-assemblies together (15 section & larger boilers) by first removing upper shipping strip and lower shipping angles from subassemblies.

Use (4) ¼”-20 x ¾” MS, nuts and washers to attach subassemblies, see Fig. 3.

e.Attach Front Intermediate Jacket Panel Support Bracket and Lower Rear Intermediate Panel Support Bracket to lower channel on Front Base Frame and

Rear Base Frame, respectively, using (4) ¼”-20 x ¾” MS, nuts and washers.

f.Base must be level in both directions and secure on the floor. Shim and grout under Base if necessary.

g.Place cardboard covering over the top of the burner assembly to protect them during the assembly of the boiler sections.

2.CLEAN BOILER SECTIONS inside and out to remove dirt due to shipment and handling.

Open Tie Rod Bundle(s). Open Draw-up Rod Bundle(s).

Open Boiler Assembly Carton(s).

3.SET LEFT END SECTION ON BASE so that locating lugs on bottom of section go inside Front and Rear Base Frames. Slide section on base until these lugs strike High Base End Panel at left end of Base, see Fig. 4. (Note – if High Base End Panel is at right end of Base, section assembly must start with Right End Section).

Left end sections are identified by “LEH” cast on section; Right End Sections are identified by “REH” cast on section.

4.CLEAN NIPPLES AND NIPPLE PORTS thoroughly with a de-greasing solvent. Use the Loctite® #592 supplied to lubricate the nipples and nipple ports. Apply the lubricant to the nipples and nipple ports, then use a brush to disperse it evenly around the nipples and the nipple ports. Use approximately 25 ml of Loctite® #592 per flueway [(1) 7” and (2) 3” nipples and their

(6) corresponding nipple ports]. Use Nipple Gauge furnished – follow instructions included with gauge to set nipples. USE ALL PRECAUTIONS TO AVOID COCKED NIPPLES.

5.PAINT ALL GROUND SURFACES of each section with the Sealer Compound furnished.

6.ASSEMBLE CENTER SECTIONS. Refer to Fig. 6 for proper location of Tapped, and sometimes plugged, Center Sections on 11 section and larger boilers. THIS IS IMPORTANT.
